Hello everyone! I am hoping someone who has used both an iPad 4th generation and a 9.7 inch iPad Pro would be able to give me their opinion. Do you feel like it is worth upgrading to the 9.7 inch iPad pro and a 4th generation iPad? Do you notice a significant performance enhancement? I am not interested in the Apple Pencil so that is not a deciding factor for me. Any opinions anyone has who has used both would be much appreciated. Thanks!
